-This installation script affects things in two ways: 1) it may do direct

+
+This installation shell script will examine your system and ask you questions
+to determine how the perl5 package should be installed. If you get
+stuck on a question, you may use a ! shell escape to start a subshell or
+execute a command. Many of the questions will have default answers in square
+brackets; typing carriage return will give you the default.
+
+On some of the questions which ask for file or directory names you are allowed
+to use the ~name construct to specify the login directory belonging to "name",
+even if you don't have a shell which knows about that. Questions where this is
+allowed will be marked "(~name ok)".
+
+EOH
+ rp=''
+ dflt='Type carriage return to continue'
+ . ./myread
+ cat <<'EOH'
+
+The prompter used in this script allows you to use shell variables and
+backticks in your answers. You may use $1, $2, etc... to refer to the words
+in the default answer, as if the default line was a set of arguments given to a
+script shell. This means you may also use $* to repeat the whole default line,
+so you do not have to re-type everything to add something to the default.
+
+Everytime there is a substitution, you will have to confirm. If there is an
+error (e.g. an unmatched backtick), the default answer will remain unchanged
+and you will be prompted again.
+
+If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
+the questions and use the computed defaults (or the previous answers if there
+was already a config.sh file). Type 'Configure -h' for a list of options.
+You may also start interactively and then answer '& -d' at any prompt to turn
+on the non-interactive behaviour for the remainder of the execution.
+
+EOH
+ . ./myread
+ cat <<EOH
+
+Much effort has been expended to ensure that this shell script will run on any
+Unix system. If despite that it blows up on yours, your best bet is to edit
+Configure and run it again. If you can't run Configure for some reason,
+you'll have to generate a config.sh file by hand. Whatever problems you
+have, let me (perlbug@perl.com) know how I blew it.
+
+This installation script affects things in two ways:
+
+1) it may do direct variable substitutions on some of the files included
+ in this kit.
+2) it builds a config.h file for inclusion in C programs. You may edit
+ any of these files as the need arises after running this script.
+
+If you make a mistake on a question, there is no easy way to back up to it
+currently. The easiest thing to do is to edit config.sh and rerun all the SH
+files. Configure will offer to let you do this before it runs the SH files.
